STR:
0) Have two or more tabs on your tab bar
1) Drag a link from an external application (I used Colloquy, Safari, and TextEdit) to the widget for the inactive/background tab
ER: Copy cursor appears on the drag, blue highlight appears on the tab widget, and dropping succeeds
AR: No copy cursor, no blue highlight, and dropping causes the drag to bounce back to the source
Dragging works as expected if you drag to the active tab's widget, to the right or left scroll arrows, to the "all tabs" widget, or to the empty tab bar area when there are not a full set of tabs.
Dragging to an inactive tab's widget worked fine in 1.6.x. I suspect some part of the tab dragging rewrite broke this, but I haven't had a chance to check.

Since this is a regression from 1.6.x (and also since it annoys me ;) ), flagging for late 2.0 consideration. Won't block on it, but if someone's out of things to work on, this would be one to look at.

Fix
I probably broke this during the restructuring to make tabs views; [self view] in this comparison is a BrowserWrapper, and only the active tab's BrowserWrapper has a window, so background tabs were always nil--which is also the drag source for any drag from outside the app.
